If a is a real number, then the real part of 4+i5a+i−i6 is( ).若a为一实数,则4+i5a+i−
In mathematics, ais almost any number you would use in real life. Real numbers include whole numbers (such as 1, 2, 3), rational decimal numbers (32.3), irrational numbers (π), and negative numbers (-4). They are called "real" to differentiate them from "imaginary" (or "complex") ...
What is a real number?Imaginary Numbers:Imaginary numbers are also called complex numbers. When imaginary numbers are squared, the result is a negative number. Imaginary numbers are used in certain calculations, such as quadratic equations. They are the result of a real number multiplied by i, ...
A real number is any positive or negative number available within the entire mathematical range of numbers. Real numbers include whole numbers, rational numbers, irrational numbers and virtually any type of number that is not an imaginary number or that can’t be computed or processed logically. ...

22.Any small interruption - a price check, a chatty customer-can have downstream effects, holding up an entire line. If there are three lines in the store, delays will happen randomly at different registers. Think about the probabil...
Give an example of a real number. What are the types of real numbers? Let x and y be real numbers. If (x + y i) - (2 - 3 i) = -6 + 4 i, what are the values of x and y? What types of numbers are NOT real numbers?
